How to Change Batteries in your Wireless Sensor Wireless Sensor

The  batteries in your Wireless Sensor will last from 2 to 5 years,  depending on use. The main factors affecting the life of your battery  are report interval and signal strength.

Note: We  recommend that you use AA Energizer Ultimate Lithium batteries; other  brands have a noticeably shorter life span. Standard alkaline cell  batteries may be used, but they do not perform well under cold  conditions.



  1. Turn the unit over and locate the screw.
